Factoring
Ninth graders factor equations and find prime numbers. In this algebra lesson, 9th graders find the factors and prime factors of a number using multiples and relatively prime numbers.
Curated OER
Applying Prime Factorization
Sixth graders use the prime factorization of numbers to find the greatest common factor and least common multiple. Working in small groups, they solve problems using the greatest common factor and least common multiple.

My Son is Naughty
Students find factors of numbers; work systematically; and use logic to explain away certain possible number combinations. They then devise and use problem solving strategies to explore situations mathematically.
Illustrative Mathematics
An Integer Identity
Challenge algebra learners to use the difference of cubes to solve this problem. Once your charges have taken out the factor (a - b), combined the like terms and set them equal to zero, the problem becomes a factorable quadratic...
Curated OER
Twenty Questions: The Hundred Chart
Use the 20 Questions game to practice math vocabulary and number properties! Project a hundreds chart and hand one out to learners. Ideally, give them counters (beans would work well) to mark off the chart so you can play multiple times....
Curated OER
Perfect Numbers
Sixth graders classify numbers as abundant, deficient, or perfect based on the relationship between the number and its factors. They review factor game using the completed lab sheet. When playing the factor game which type of numbers...
Curated OER
Pascal's Triangle
Young scholars explore the concept of Pascal's Triangle. In this Pascal's Triangle lesson, students use an applet called 'Coloring Multiples' to explore Pascal's Triangle. Young scholars develop patterns starting with various numbers in...
Curated OER
Paper Pool
Learners analyze the measurements of rectangles. In this analysis lesson, students will investigate patterns by looking at ratios. Learners will also hypothesize the probability of a ball going into a certain pocket when playing pool....

Quickies Final Hints And Answers
In this math worksheet, students examine the numbers while looking for the number patterns. They determine the values of the missing variables.
Curated OER
Pascal's Triangle
Students study Pascal's triangle. They construct their own version of Pascal's triangle, and relate some of the uses for it. While working through this process, students practice their integer multiplication and division skills.
Curated OER
The Five Number Game
Students explain what it means to square numbers. They explain what it means to cube numbers. Students define prime numbers using their own language. They are introduced to the problem by playing one game as a class.
Curated OER
The Quadratic Formula
Students solve quadratic function by completing the square. In this algebra lesson plan, students use the quadratic formula to factor quadratics and find the roots. They graph the parabola and identify its properties.

And the Number Is (Second Grade)
Second graders create Mystery Numbers. They give the class clues about the name, value, and multiples of the digits which make up the number.
Curated OER
Patterns in Pascal's Triangle
Students examine the patterns that exist in Pascal's Triangle. They explore multiples and factors. Sudents use an applet to create and color the multiples in Pascal's Triangle.
Curated OER
The Commutative Cookie
Third graders investigate the commutative properties of multiplication and focus upon the setting of cubes in the correct patterns to solve problems. They differentiate between numbers that have multiple factors and prime numbers....
